alo, i will soon be starting the mammoth task of archiving my music and games(audio tracks) collection, and have a few questions..

1. All lossless codecs give 100% quality right?2. So which codec will give me the smallest file sizes with that 100% quality.3. And will it decode back to wav with 100% quality.

4. before i knew about lossles compression i tried ogg vorbis at (quality 10)500kb vbr, and with my computer speakers couldnt hear any difference. So is it my speakers, me or at that setting is it lossless or close to lossless.

The great thing about lossless, is that it doesn't matter what you choose. If you change your mind later, just convert them all.

Yup, "just" convert You don't loose quality, but it is a great pain... takes a lot of time, you have to do some work to preserve all tags properly, replaygain info is usually lost and has (or at least should) be calculated again for new files.

No it shouldn't. The audio will be identical, and so will the RG information. lossless - remember?
